The Email.sc.edu Leak Gave Hackers 6,540 Working Passwords

The email.sc.edu leak gave hackers 6,540 working passwords after a Telegram user uploaded a stealer log file on 10-Jun-2026. HEROIC analysts reviewed the dataset and confirmed it contains email addresses, plaintext passwords, and the URLs those credentials were used on.

Why This Is Dangerous

With this file in hand, an attacker has everything needed to attempt direct access to 6,540 accounts. Each password sits next to the exact login URL it was captured from, so there is no guessing involved, just a straightforward attempt to log in using data pulled from an infected device. That is a much faster path to account access than trying to break in through brute force or phishing.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

Because these passwords are in plaintext, they are usable immediately, with no cracking step required. If any of these 6,540 people reused their password on another account, attackers can attempt credential stuffing against email, banking, or shopping logins. That kind of access frequently leads to account takeover, identity theft, or direct financial fraud.

How Stealer Log Leaks Work

Stealer log malware typically spreads through cracked software, fake downloads, or malicious email attachments. Once it infects a device, it silently extracts saved browser passwords and autofill data, then sends that information back to the attacker running the malware. The stolen data is compiled into a log file and shared or sold on Telegram channels and dark web forums, often within days of infection, which is why stealer log credentials tend to still work when they surface.

Check If You Are Affected

If you have ever used a login connected to email.sc.edu, or you tend to reuse passwords across accounts, it is worth checking your exposure today. HEROIC's free breach scanner searches more than 400 billion leaked records, including stealer log data like this one, to tell you whether your email has surfaced. Run a free scan and update any reused passwords immediately if you find a match.
